Application filed July 17, 1917, Serial No. 180,974. Renewed December 81, 1918. Serial No 269,178.

To all whom it may concern:

Be it known that I, JAMES E. Smrson, a citizen of the United States, and-resident of the boron h of Brooklyn, county of Kings,

machines of various makes or forming a per-' manent part of the equi ment thereof, whereby in the movement 0 the paper carriage longitudinal lines may be drawn, and in the revolving movement of the platen vertical lines may be drawn.-

One of the objects of the invention is to provide a line ruling device which is normally out of contact with the paper platen but which may be moved to cause the line ruling wheel to engage the platen, yieldable means being provided to hold the line ruling wheel in the desired relation to the platen.

Another object of the invention is to provide a line ruling device with a line marking wheel and a rotatable inking roll, and to cause the inking roll or pad to move transversely of the line markm wheel whereby substantially the entire sur ace of the inking pad will be caused to engage the marking wheel. The purpose of this is to prevent the marking wheel wearing a groove in the inking roll.

Another object of the invention is provide means operated through the rotation of the marking wheel to shift the ink ng roll laterally to thereby cause substantially its entire inking surface to contact with the marking wheel.

Another object of the invention 18 to provide a rotatable holder carrying the marking wheel and, the inking roll, and to prov1de a stop to limit the rotary movement of the said holder and to enable the operator to accurately position the marking wheel for ruling either horizontal or verticaldines.

There are other important objects and advantages of the invention all of which will appear more fully hereinafter.

In the drawing, Figure 1 is a vertical longitudinal sectional view taken on the line 1-1 of Fig. 2;

Fig. 2 a plan view of the device applied to a typewriter frame;

Fig. 3 a transverse vertical section v' on the line 33 of Fig. 2; a1 lew Fig. 4 a longitudinal vertical sectional view on the line 44 of Fig. 2; and Fig. 5 a detail side elevation of the markingiwheel.

eferrin to the various parts by numerals, 1 esignates a permanent part of a typewriter frame, and 2 the platen. Secured to the typewriter frame is an upwardly extending bracket 3, in the upper end of which is formed a horizontal ournal part 4. Mounted 11111115 Journal is a horizontal rod 5, carrying at its forward end a finger piece 6 by means of which the bar 5 may be rotated and ressed rearwardl as hereinafter descri ed. The bar 5. is ormed with a s uared rear portion 7, on the rear end of w ich issecured a rearwardly extending frame 8. Between the finger piece 6 and the Journal bearing 4, and surrounding the rod 5, is a spr ng 9 which normally retracts the bar and holds the stops 10 and 11 against the ournal bearing. Secured to the bracket 3 and bearing against one side of the squared portion 7 of the rod 5 is a fiat spring 12, said spring serving to hold the rod and the connected frame 8 in either the position shown in Fig. 1 or in a partlz; rotated position in which the line ruling w eel will be in a horizontal position, as will be hereinafter described.

In the rear end of the frame 8 is mounted a shaft 13 to which is secured the line ruling or marking wheel 14, said wheel beingformed with a narrow periphery for marking purposes and which is adapted to be brought into engagement with the paper sheet on the platen 2. Carried by the markin wheel, on one side thereof, is a cam 15, said cam extending only partly around the marking wheel as indicated clearly in Figs. 2 and 5. Loosely mounted in the frame 8 is a transverse journal rod 16, said rod extending loosely through apertures 17 in the sides of the frame 8. Loosely mounted on this journal rod is an inking roll 18 which is adapted to bear against the periphery of the marking wheel 14, the said inking roll being somewhat larger in diameter than the marking wheel as shownklearly in Figs. 1 and 2 of the drawings. Ri idly secured to the forward cross bar 19 o the frame 8 are two springs 20 whose rear ends engage in grooves in the journal bar close to the inner surfaces of the side bars ofthe frame 8, as shown clearly in Fig. 2, said springs fencing! the journal. bar rearwardly and! causing the inking roll to y eld-mgly enggge the'periphery of the marking w eel. he springs 20 also serve as latch devices for holding the journal bar in position in the frame 8. The inking roll may be removed from the frame-by forcing the journal bar.

axially through the frame, the springs 20 yielding to a suitable endwise pressure on said bar. Loosely pinned to the forward cross bar of the frame 8 is a rearwardly extending yoke 21, the arms 22 of which extendon either side of the inking roll and are apertured for the passage of the ournal rod. The rear end 0 one of said arms 22 is ada ted to be engaged by the cam 15 on the marking wheel and to follow said cam during the rotation of said wheel. A spring 23 is carried by the frame 8 and bears against the outer side of the arm 22 which engages the cam 15, and. yieldingly holds said arm in engagement with said cam. The yoke '21 is loosely pinned to the frame 8 in order that it may be moved laterally by means of the cam 15. The arms 22 of sald yoke are close to the sides of the inking roll so that as the yoke is vibrated laterally it correspondingly moves the inking roll on the journal rod.

The bracket 3 is formed with a rearwardly extending stop lug 24 which is adapted to be engaged by the lugs 10 and 11. When the stop lug 11 is in engagement with the stop lug 24 the marking wheel 1s in position to rule vertical lines on the paper carried by the platen 2. By rotating the bar 5 in the direction indicated by the arrow B in Fig. 3, the lug 10 will be brought into engagement with the stop lug 24: to hold the marking wheel in a position to roll horizontal lines on the paper carried by the platen. To bring the stop lug 11 into engagement with the stop 24 the rod 5 is rotated in the direction indicated by the arrow marked A in- Fig. 3. The spring 12 serves to yieldingly hold the rod 5 in its adjusted position, the cooperating stops 10, 11 and 24 serving to accurately position the marking wheel for marking. either horizontal or vertical lines, as desired. The stop lug 24 is of sufficient length to permit the lugs 10 and 11 to remain in engagement therewith when the frame 8 is projected rearwardly to bring the marking wheel into engagement with the paper carried by the platen.

It, is manifest that by reason of the variation in the diameters of the marking wheel and the inking roll the periphery of the marking wheel will eventually be brought into engagement with substantially the entire inking surface of the inking roll. It is also manifest that the marking wheel will not run in thesame path on'the inking roll throughout the rotation of said roll, but that the said path will vary in successive rotations of the inking roll andthat all danger of. wearing a groove or fixedpath or orbit in'the inking roll will be avoided.

It will, of course, be understood that any suitable means may be employed for supporting the inking roll to permit, it to have a lateral movement through the operation of the marking wheel. It is also manifest that the details of construction may be considerably yaried within the scope of the invention; for instance any suitable means may be provided for stopping the rod 5 at the proper points in its rotation to accurately position the marking wheel for ruling either horizontal or vert1cal lines.
